Abstract: ABSTRACT OF THE DISCLOSURE    A composition and method for immunizing carnivores and other mammals, especially foxes, against rabies and other pathogenic diseases, by setting out and orally administering a dose of a vaccine, are described.  The vaccine  is  enclosed  in a bite-permeable  sponge-like vector and the container is coated with a membrane containing an attractant, such as tallow.  The method operates  by  penetration  of  a  sponge  resulting  in distribution of relatively large volumes of vaccine to the oropharyngeal cavity of the mammals.

Abstract: Abstract of the Disclosure A downhole packer assembly includes a first packer tool with a flexible tubular packer body which is radially extend-able by virtue of fluid pressure in a packer set chamber.  A generally annular packer foundation, including an upper packer head, is connected to the upper end of the packer body. The tool defines a bypass flow system for permitting flow of fluid from the packer set chamber to a central longitudinal flowway of the assembly and from this central flowway to the exterior of the assembly.  A control sub adjacent the packer foundation is movable with respect to the packer foundation between a first position, for opening the bypass system, and a second position, closing the bypass system.   The control sub is preferably further operative, in its first position, to permit communi-cation between the central flowway and the packer set chamber, and in its second position, to close the packer set chamber. A second packer tool is connected in tandem with the first tool. A ported cylinder is communicatively connected to the packer foundations generally below the locus of the control sub and has a piston reciprocably disposed therein and sealed with respect thereto, the piston being yieldably urged toward the control sub.  A plug ejector may be adjoined to the upper packer head of the first tool and disposed therein but adapted to permit flow therethrough.  The plug ejector has a free end extending upwardly and positioned for telescopic movement with respect to the lower end of the control sub as it moves between its inflation and set positions.

Abstract: ABSTRACT            A pump with a continuous inflow and a pulsating outflow comprises a first chamber and a second chamber with a passage between them and made from a flexible material, provided with an inlet to the first chamber and an outlet from the second chamber, the passage between the chambers being provided with a one-way valve permitting flow in direction from the first to the second chamber only, and a second one-way valve arranged at the outlet permitting flow out of the second chamber only. The chambers are movably supported in a pump casing with a first and a second opening, in that the inlet is connected to and penetrates the first opening, and in that the outlet is connected to and penetrates the second opening. Drive means cyclically affect the second chamber and reduce its volume under expulsion of the medium which is pumped while simultaneously affecting the walls of the first chamber causing its volume to increase and medium to flow through the inlet into the chamber. The drive means include a drivering surrounding said passage and fixed to it, and which drivering has surfaces engagable with the first and the second chamber walls in a way that the medium taken in between periods when the drive means is affecting the chamber walls controls the output of the pump by defining the receding movement of the drive ring, which movement is a function of the differential pressure force resulting from the difference in areas of engagement with the respective chamber wall on both sides of the drive ring.

Abstract: ABSTRACT OF THE DISCLOSURE            METHODS OF MAKING METAL CAN ENDS WITH PLASTICS CLOSURES            A method of making a metal can end with a tear-open plastics closure, for a can intended to be resistant to leakage when subject to internal pressures, such as arise from carbonation of a beverage or thermal processing, wherein the undersurface of the can end is provided with a plastics coating, and the can end is pierced to form an aperture with a peripheral downturned flange at an angle of 80° to 120° to the plane of the can end and having a flat end.  A one-piece ring pull closure is injection moulded on to the can end from a plastics material resistant to softening at up to at least 65°C, without additional heating of the metal, so as to fill the aperture, bond with the coating, and enclose the flange, with a residual thickness below the flange of 0.08 to 0.5 mm.  The thickness of the plastics material of the closure is such that it can be sheared against the flange when the ring pull is pulled manually.  The residual thickness of the plastics material may be varied around the aperture to increase resistance of the closure to creep, and the aperture may be pear-shaped or may be circular with a separate vent hole.

Abstract: Abstract Film Coolant Passage With Swirl Diffuser The wall of a hollow turbine airfoil has a longitudinally extending coolant outlet slot in its external surface which intersects, along its length, a longitudinally extending cylindrical channel within the wall.  Metering passages extend from the inside surface of the airfoil wall to the cylindrical channel and direct a metered amount of coolant into the channel in a manner which results in a swirling motion being imparted to the fluid as the fluid diffuses within the channel.  The coolant is thereupon ejected from the channel through the slot in the external surface as a film on the external surface of the airfoil along the length of the slot.  The swirling of the fluid within the cylindrical channel helps diffuse the fluid such that the outlet slot becomes completely filled with coolant, whereby a film of coolant is created on the airfoil surface downstream of the slot over the full length of the slot.

Abstract: FAULT RECOVERY IN A DISTRIBUTED PROCESSING SYSTEM     Abstract A fault recovery method for a distributed processing system where a message called a heartbeat is broadcast among the processors once during each major processing cycle.  The heartbeat message indicates the physical (PMP) and logical (LMP) identity of the transmitting processor with respect to the system arrangement as well as the processor's present operational state.  By monitoring the heartbeats from other processors, spare processors can autonomously take over the functions of failed processors without being required to consult or obtain the approval of an executive processor.  The new physical location (PMP) of a replaced processor will be automatically recorded by the other processors.  The method has application to duplex standby and resource pool configurations as well as sparing arrangements.

Abstract: ABSTRACT OF THE DISCLOSURE         A gearshift lock for the shift mechanism of a manually operated multiple speed ratio transmission includes a selector shaft rotatable by a gearshift lever under the control of the vehicle operator, a selector finger movable within slots formed in a base plate, the slots being defined by the various positions of the gearshift lever that correspond to speed ratios of the transmission.  A spring-loaded rotatable locking cam mounted on the gate plate cooperates with a finger carried on the selector shaft to prevent backward shifting movement from a forward gear position into the reverse gear position and to guide the selector finger into the adjacent gearshift slot.  A base plate pivots on a pin fixed to the gate plate against the force of a legged spring to produce a sensible indication to the vehicle operator when greater force is required to move the gearshift lever.

Abstract: It is usual for postal packages to be delivered to mail sorting offices by tipping them out of trucks, and for staff then to have to read off the destination details of individual packages and key these into a sorting system for the packages.  This calls for considerable manual effort, and for desirable automation of the work the invention specifies that by using various dynamically acting handling stations, each of which only acts on the packages in a simple manner, the desired result can be achieved without the use of more expensive handling stations.  The invention ensures that a pile of packages received is delivered as a flow of individual packages with machine-readable destination codes (figure 1). <IMAGE>
